畜禽骨蛋白水解及多肽螯合钙研究进展

Current Status and Progress of Studies on Protein Hydrolysis of Livestock and Poultry Bones and Peptide Chelated Calcium

畜禽骨骼是一种量大并且营养十分丰富的天然资源,但是我国对畜禽骨骼的深加工利用率不足1%。本文针对国内外畜禽骨骼的开发利用现状,结合畜禽骨骼的组成与结构特点,对畜禽骨胶原蛋白水解方法和主要功能性水解产物及其分离纯化方法展开阐述,并重点探讨了畜禽骨胶原多肽螯合钙新型补钙产品的开发研究,对其螯合工艺的主要影响因素以及螯合物的吸收性进行了详细的介绍。最后预测了我国畜禽骨骼制品的开发前景。

Livestock and poultry bones are abundant natural resources very rich in nutrients; however, only less than 1% of these resources in China are in depth processed or utilized. This article reviews the current situation in the exploitation and utilization of livestock and poultry bones at home and abroad with respect to chemical composition and structural characteristics, hydrolysis methods, major functional products, and techniques for their separation and puriifcation, with emphasis on the development of bone peptide chelating calcium as a new calcium supplement. A detailed elucidation of the major factors affecting the chelating process as well as the absorption of the chelate is also given. Finally, the future prospect of bone products in China is predicted.
